does the drive light flash twice at startup?
or once
the option in the hbc means you have it installed as an ios

It only flahes once, I have tried everything I can but I can not get bootmii to boot or run of the sd card, as I can not run any games either the 4.3 hack is no good, I think till a hack which can be done without using a game comes out ( if ever) it is stuffed.
but thanks for all the advice
